Dynamic Air Quality Sticker for Emission Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for improving air quality in urban environments, such as Regulated Critical Areas, are limited by their reliance on expensive and bulky instrumentation to measure vehicle emissions, which cannot account for varying driving styles and modes of transport, excluding non-car mobility and lacking a comprehensive method for estimating local pollutant emissions.
Innovation Solution
A smartphone-based system that uses computing models to estimate local pollutants without additional sensors, integrating with connected vehicles to measure and calculate pollution emissions from both vehicles and user mobility, providing a dynamic 'air quality' sticker for real-time access control to restricted areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If expensive and bulky instrumentation systems are used to measure vehicle emissions, then measurement precision is improved, but device complexity and cost increase, making large-scale deployment impossible
Solution Approach 1:
The patent uses software-based emission estimation models that replicate the functionality of physical measurement systems through computational algorithms. Instead of deploying expensive physical sensors in every vehicle, the system uses software estimators integrated into connected vehicle systems to calculate emissions based on vehicle parameters, traffic conditions, and driving behavior, providing a cost-effective alternative that maintains measurement accuracy
Solution Approach 2:
The patent replaces mechanical/physical measurement systems with software-based computational models. Emission estimation is performed through algorithms that process data from connected vehicle systems, replacing the need for physical emission measurement instrumentation while maintaining the ability to assess emission levels accurately
2Ease of operation
If traditional air quality stickers based solely on vehicle year and fuel type are used, then ease of operation is improved, but adaptability worsens as they cannot account for varying driving styles and transport modes
Solution Approach 1:
The patent transitions from static emission stickers to dynamic emission estimation that continuously updates based on real-time data. The system adapts emission calculations to current driving conditions, traffic patterns, and vehicle performance, allowing the emission assessment to change dynamically rather than remaining fixed based solely on vehicle age and fuel type
Solution Approach 2:
The patent incorporates multiple varying parameters into the emission estimation model, including driving style, traffic conditions, vehicle load, and transport mode. This allows the system to adjust emission assessments based on actual usage patterns rather than relying on fixed vehicle characteristics alone
3Adaptability or versatility
If comprehensive measurement of overall user mobility including soft modes is implemented, then adaptability is improved, but device complexity increases requiring integration of multiple detection systems
Solution Approach 1:
The patent uses a multi-functional approach where a single connected vehicle system serves multiple purposes: it detects hard modes of transport, estimates emissions for motorized vehicles, and detects soft modes of mobility. This unified system replaces the need for separate detection systems for different transport modes, reducing overall system complexity while maintaining comprehensive coverage
